SegWit2X network doesn't exist, there is no mainnet, not one single working node.
What's even worse is that except maybe 2 people here nobody cares. People are talking about some conspiracy theories instead of focusing on the facts, i.e. there is no fucking mainnet at all. This blockchain doesn't exist.
Focusing purely on the facts: several working nodes have been posted in this thread. e.g. 136.243.147.159.
There's a partly working block explorer here:
http://miningpool.shop/site/block?id=2043 - I had to try it a few times before it loaded and even then it doesn't work very well.
Most recent block is 502182, difficulty 8.6M.
